We've spent 4 full days in the island Ilha Grande.This island is a one big jungle with a well developed set of trails for independent hiking to the beaches. The only cars on this island belongs to the emergency services and everything is done by foot or by boat. We took a boat to get to Lopez Mendez beach where we chilled to whole day and matan took a surfing lesson in Portuguese and managed to catch long waves to the beach with a beginners surfboard. The next day we took a 2:15 hours (each way) trail to the remote beach of Dois Rios, a beach with one river on each side, thus its name.Some of the animals we saw here are: squirrel monkeys, very big lizards, squirrel, lots of kinds of butterflies.Here we also ate acai for the first time, it's some kind of cherries smashed and frozen, served with granola, bananas and honey - very good !Anyway, the beaches here were really amazing and the island with its huge green mountains too.
